    • One embodiment of the invention relates to a signal conversion system for converting an asynchronous signal to an isochronous signal to permit displaying network-delivered digital content on a television device. A computing device acts as the source or storage of digital video content. A conversion device is communicatively coupled to the computing device to receive asynchronous digital video content. Either the conversion device or the computing device identifies two or more reference markers in the asynchronous video stream and determines a clock rate from the known time interval between the two or more reference markers and the amount of video content received between the two or more reference markers. The conversion device generates an isochronous digital video stream having the video content at an interval corresponding to the clock rate. The clock rate in the isochronous signal approximates an original clock rate for the digital video stream.
    • 本发明的一个实施例涉及一种用于将异步信号转换为同步信号以允许在电视设备上显示网络传送的数字内容的信号转换系统。 计算设备充当数字视频内容的源或存储。 转换设备通信地耦合到计算设备以接收异步数字视频内容。 转换装置或计算装置都识别异步视频流中的两个或更多个参考标记,并且从两个或更多个参考标记之间的已知时间间隔和在两个或更多个参考标记之间接收的视频内容的量确定时钟速率 。 转换装置以与时钟速率对应的间隔产生具有视频内容的同步数字视频流。 等时信号中的时钟频率近似于数字视频流的原始时钟速率。
